Phenol distillation

Hello people,
I wonder if anyone can advise me: I am about to start extracting DNA for
PCR RAPD's. I have been advised that the easiest extraction in these
circumstances is an ordinary phenol/chloroform extraction, followed by
dialysis to get rid of remaining phenol.
My supervisor (thinking I just had reagent grade phenol) advised me to
redistill it before use. I have distilled some (not a pleasant job) but
after an accident yesterday in which a flask of boiling phenol was broken,
I am reluctant to carry on. Further, my supervisor has just discovered
that I do have AR grade phenol (from BDH) and suggests that further distill-
ation may not be necessary.
Can any of you suggest whether distillation of new AR phenol should be
necessary?
Thank you,
Hal
